K'nex BM Element - 2x2 Dropper



About: Finally back, this time with my new Ball Machine, Helios! If you like it, thanks! Otherwise, thanks anyways for knowing what it is!

My second BM Element, after the White Wheel Lift. It can perform the functions of a path selector, a dropper, and a pair of maracas - all at the same time!

Step 1: Parts List

The pieces you'll need for the 2x2 dropper are -

2 x Yellow Rods

1 x Orange Connector

2 x Large Wheel

2 x Hubcap Wheel (Large) w/ Tyre

Step 2: Building

Just assemble it as shown in the pictures, it's pretty simple.

Step 3: Done!

If you've made it, and are happy with its performance, post an IMI for support! I'll add those pictures to this step.

    Put a rod slightly above the support, and the dropper becomes a Ball Alternator.
